What is a way of learning about the natural world by gathering information and exploring that information?
Science
using one or more of your senses to gather information
observation
How are experiments designed and conducted?
An experiment must follow sound scientific principles for its results to be valid.
creating representations of complex objects or processes
model
grouping together items that are alike in some ways
classification
What is an example of a scientists observing using sight and hearing?
(reflective of student answer)
Make a reasonable inference right now.
(varies)
What is scientific inquiry?
The way in which scientists study the natural world AND propose explanations based on evidence they gather.

Which process is related closely to a person's five senses?
Observing
define dependent variable

Is this statement an inference or prediction?(The cat will fall)
Prediction
How is a data table (independent and dependent data) organized?
The first column is the independent variable, and the second column has the dependent variable
Why is observation such an important scientific process?
Scientific Investigations involve observations about one or more aspects of the natural world
define independent variable
the one variable that is purposely changed to test a hypothesis
Why do scientists make models?
To represent complex objects or processess that cannot be directly observed
Which processes would be considered mental and not physical?
Inferring, predicting, classifying, evaluating
Which processes might require a scientist to do tasks in a series of steps?
Making models, conducting scientific investigations, etc
